Abstract
Software Defined Networking concepts apply to access, fronthaul, backhaul and core networks of 5G mobile networks and beyond. Such network components currently have individual/segmented control planes and associated controllers to provide configurability, provisioning, and network slicing. This is because of technology disparity between these network components: access is wireless/cellular, backhaul and fronthaul are optical/fiber, and core is electrical/wire-line. A system/method is detailed that enables a coordinated and unified end-to-end slicing, wherein the coordination is provided in the system/method that (a) attaches to the respective controllers of these network components in real-time, (b) collects the connectivity topology of each network segment as the network evolves, (c) passes the slice-profile information (translating according to capabilities of that network segment to configure an end-to-end slice with a specified bandwidth requirement and service quality level), and (d) passes across a VLAN tag to be used across network segments to associate with the same slice.
